If anything changes in the way we purchase and play games, it will not be a MS only thing...everyone wants the used game market to get killed. Gaming is going to change, period, we just dont know how yet. I see something happening like Games will have a product key, like most computer software, and it has to ge activated, similar to most MS software now. You log into your profile on XBOX Live, activate your game, then the game will only work if that profile is signed in on whatever console. Like it will tie the game to YOU. Most Downloaded games work this way now. When I purchased Minecraft for xbox, I downlaoded it on all my consoles, the game works for every profile on the xbox it was purchased from no matter what, but the other consoles, my profile has to be signed in before the game will start, then I can sign out and let the kids sign in to play. This is the direction I see every console going in the future.
Personally, I dont see the big game makers deal with the used game market, I mean if they want to make it illegal (and they do) to sell used games....then only to be fare, we should not be able to buy used cars, used furniture, used clothing, used records, or used ANYTHING. Cause GM didnt make a DIME when I purchesed my wifes 1995 Z28, and I guess thats just not fare. I think me, you and anyone else should be free to do whatever the hell we want with what we purchase after we pay our hard earned money for it, PERIOD.
